Effect: The burst creates a zone filled with tangled webs until the end of the encounter or for 5 minutes. The zone is difficult terrain. Any creature that enters the zone or starts its turn there takes 4d6 + Charisma modifier radiant or necrotic damage. Any creature that ends its turn in the zone becomes immobilized (save ends).

Special: The damage type of this power is determined by your alignment; if you are good aligned then this power deals radiant damage; if you are evil aligned this power deals necrotic damage. Unaligned characters may choose the damage type of this power (either radiant or necrotic).
